Leak detection methods are broadly classified into two categories: external leak detection methods (i.e., aerial patrol and on-site inspection) and internal leak detection methods (i.e., pressure-flow monitoring and computational pipeline monitoring).
Some segments along transmission pipelines have been designated as high consequence areas (HCAs) in accordance with the Pipeline and Hazardous Materials Safety Administration (PHMSA) guidance and federal regulations. HCAs, for hazardous liquid pipelines, are defined as populated areas, drinking water sources and unusually sensitive ecological resources.
Supplemental hazard assessment and prevention programs have been developed for HCAs that provide comprehensive management of threats to asset integrity. This is done by identifying and assessing integrity risks associated with the pipeline and managing these risks to a level as low as reasonably practicable.
Our Canadian Valley natural gas processing plant in Calumet, Oklahoma, completed a project to capture and divert hydrocarbon condensate inside the plant caused during the cooling process in order to eliminate the potential risk for condensate to make contact with the ground.
